an established connection was aborted by the server

[Ram_NiwasVerma1]

Hi All,

We are facing issue while running the unix command. Running as simple command as "ls" is returning "an established connection was aborted by the server".

We are running the unix command through code stage:
try
{
ConnectionInfo connectionInfo;
connectionInfo=getConnInfo(Host,Username,Password,keyLocation);
var sshclient = new SshClient(connectionInfo);
sshclient.Connect();
SshCommand sc = sshclient.CreateCommand(Command);
sc.Execute();
Response = sc.Result;
sshclient.Disconnect();
}
catch (Exception ex)
{
Exception=ex.Message;

Even when we are trying to run this code outside of the blueprism say for visual studio we are getting the same error.

Please suggest.

Thanks.

Ram,

You might raise this issue with the maintainers of the SSH library you are using, since it is not specific to Blue Prism as you stated. When a code block works in Visual Studio, you can reasonably expect it to work in Blue Prism.

That said, there are a couple of areas you might check:
1. Does your server have any logs reporting the specifics of the connection error?
2. Can you connect via SSH using a tool like Putty?
3. Is your host key algorithm compatible? Check the key algorithm used by the server and see if it is compatible with the SSH library. I believe, with SSH.NET, there are cases where some key algorithms are simply incompatible currently. The developers of SSH.NET would be of the most guidance in that scenario.
